We run a D2C brand selling through both our own site and third-party marketplaces (Amazon, Faire). When Gemini answers product queries, it attributes to the marketplace listing instead of our DTC site—even though we have better brand control, fresher product info, and schema.org/Product markup on our canonical URL. We've set canonicals pointing to our site, but Gemini seems to ignore them. Should we be using schema.org/manufacturer or brand relationships to signal DTC authority, or is this a fundamental limitation where answer engines just prefer 'neutral' marketplace URLs over vendor-owned domains?

Asked by Emma R.
Gemini sees marketplace listings as more trustworthy (third-party validation), so schema alone won't flip this. Add schema.org/brand + manufacturer relationships on your DTC product pages, but more importantly: get marketplace listings to link back to your canonical URL with rel=canonical or explicit brand attribution. Better move—build brand authority outside product pages (reviews, press, industry mentions) so Gemini understands your domain as the authoritative source, then use Product schema to connect DTC pages to that entity context.
